W. ATTENDANT WHEEL LOCK INSTALLATION
1. Remove wheels from chair.
2. Attach Mount bracket/cable assembly to axle strut tube using 1/4" x 1-3/4" bolt (item
14) with nut and washers.
3. If push-to-lock wheel locks are already installed, remove the push-to-lock assemblies
by removing the M6 bolts (item 6) and adjustment nuts (item 9), leaving the slide plates
mounted on the chair, and go to step 5. If there are no wheel locks mounted already,
proceed with step 4.
4. Attach Wheel Lock Slide Plates to Roller Assembly on each side of the chair using 1/4"
hex bolts (item 10) and Mounting Block (item 8). If axle of rear wheel is above the base
frame tube, orient the slide plates upward. If the axle of the rear wheel is below the
base frame tube, orient the plates downward. Plate may be flipped forward or
reversed as needed for different wheel sizes.
5. Attach the left and right Remote Lock Assemblies (item 4) to the slide plates using the
Attendant Wheel Lock Spacer Blocks (item 3), M6 x 60 screws (item 6), lock washers
(item 5), and Wheel Lock Adjustment Nuts (item 9). The adjustment nuts marked “R”
and “L” are to be mounted to the right and left side of the chair respectively. The
smaller protruding oval shape on the nuts should slide inside of the slot in the slide
plate. Do not tighten bolts. Slide the Remote Lock Assemblies as far forward as they
will go.
6. Re-install wheels and slide the Remote Lock Assemblies rearward until the friction
block of the remote lock is approximately 1/4" (6mm) away from the tire when
unlocked. If the lock cannot be adjusted to this position, you will need to adjust the
position of the slide plate until it can be adjusted as stated. Once remote locks are
properly positioned, tighten bolts.
7. Attach cables to Remote Lock Assemblies by sliding the stud at the end of the cable
into the slot in the Remote Lock Assembly. Pull back on the cable sheath and slide the
end of the cable sheath into the pocket on the Attendant Wheel Lock Spacer Block
(item 3) as shown. Be sure that the cables are routed away from all moving parts.
Attach the cables into place on the chair with zip-ties provided.
8. Adjust the cable adjustment screws (item 24) as necessary to ensure that the wheel
locks can get to their fully extended position when the pedal is engaged. Position of the
Remote Lock Assembly may need to be fine tuned to optimize the force needed to
engage the pedal, depending on tire type. If excessive force is needed to engage the
pedal, cable life may be reduced. Once proper adjustment is attained, lock cable
adjustment screw in position by tightening jam nuts against mounting block.
